cell phone jammer can disable the spy recorders around.
But too much information on the SIM card cell phone will from time to time to read the data, can also cause power loss. Transmitted by the cell phone network as well as efficiency of the system.

According to the GSM system design, cell phone base station transmit power according to the instructions will automatically adjust the cell phone far away from the base station, or in a signal

shadow area, or cell phone transmitting antenna system efficiency is low, the cell phone will have to transfer large transmission power, then the mobile power will be multiplied. And not to say

that when the cell phone call was launched, usually cell phones and networks have to keep in touch regularly report to the network work, so the network and mobile antenna systems for cell phone

standby time also plays a very important role.If your GSM network

supports this function, this function will automatically open. Make voice clearer, hear more real. STK: STK (SIM TOOL KIT), referred to as "user identification application development tool", can be

understood as a value-added business development order, a small programming language. cell phone jammer is well received in the education department.
It allows smart card-based user identity module SIM to run their own applications. STK card is not an ordinary SIM card is usually used, but the Java-based platform Simera32K card. STK is a small

programming language software, you can cure the SIM card. It can receive and send short messages to GSM data, play a short message between the SIM card and the role of the interface, it also allows

a SIM card to run their own applications. These functions can often be used to activate the software on the cell phone display, a friendly text menu instead of mechanical "dial-up - Listen -

response" approach, allowing users to easily perform complicated key information retrieval operation or transaction. cell phone jammer needs more improvements to meet the new requirements.
SIM card technology, \ "over the air \" business, SIM card-based services, such as moving "Monternet" SIM card, "M-Zone", which are based on STK SIM card technology, the technology can make the SIM

card with large storage capacity and built-in operators of the services provided. STK can be understood as a set of value-added business development order, a small programming language that allows

smart card-based user identification module (SIM card) to run their own applications.
